Where 110 sits on the IQ scale
A score of 110 is 10 points above the mean. Dividing by the standard deviation gives (110 − 100) ÷ 15 = 0.67. The normal cumulative distribution converts that standardized position into percentile 74.75.
This lies in the upper half of the central 85–115 interval. It is above the scale mean, but the total alone does not identify a particular strength in memory, numbers or spatial reasoning.
How common is a score of 110?
Approximately 25.25% of this model lies at or above 110—about 1 in 4. This is a cumulative share, not the chance of scoring exactly 110. A continuous model does not assign a positive probability to one exact value.
Compared with IQ 100, the reference percentile is 24.75 percentage points higher. Equal IQ-point gaps do not create equal percentile gaps: the middle of the bell curve contains more area than its ends.

How this relates to starp
starp's current scoring map does not produce exactly 110. Its neighboring results are 109 for 24 correct answers and 115 for 25 correct answers out of 30. This guide explains the conventional scale value 110; it does not invent an intermediate starp result.

Questions about IQ 110
Is 110 a good IQ score?
110 is above the reference mean of 100. It is a higher score on that scale, but a number alone cannot establish a specific skill profile or predict success.
What percentile is an IQ of 110?
On a normal scale with mean 100 and standard deviation 15, 110 corresponds to approximately percentile 74.75. Around 25.25% of that model lies at or above it. Use an assessment's own norms for an actual reported rank.
Does an IQ of 110 mean 110% correct?
No. IQ is a scaled score. Percentage correct depends on the questions and scoring rules; percentile describes a relative position. These three quantities are not interchangeable.
